UNITED- STATES LYMAN F. MCNET", OF YONKERS, NENV YORK, ASSIGNOR TO THEAMERICAN MOTOR COMPANY, OF NEW YORK, N. Y.

COMBINED GAS-ENGINE AND CARBURETOR.

SPECIFICATION forming part of Letters Patent No. 407,961, dated July 30,1889. Application filed September 15, 1887. Serial No. 249,800. (Nomodel.)

To all whom it may concern:

Be it known that I, TA'M'AN l NONE'P'I, a citizen of the United States,and a resident oi. the city of Yonkers, county of \Vestchestcr,

5 and State of New York, have invented a new and useful Improvement inombined (hrs-Engine and Carburetor, of which the following description,in connection with the accompanying drawings. is a specification, likeletters on the drawings represcntinglike parts.

My invention relates to an organization of apparatus in which watercirculated in such manner as to keep the cylinder of a gas-engine cool,and to heat a gas-generator for carbureting air with naphtha or othervolatile hydrocarbon to make gas.

My invention consists in the combination of apparatus hereinafterdescribed, and comprising exhaust and inlet pipes properly arrangedbetween a jacket for the gas-engine and a jacket or reservoir for agas-generator by which air maybe carburctcd with naphtha or othervolatile hydrocarbon, as will be hereinafter more fully described.

The cylinder of a gas-engine must be kept cool while in operation, whichis ordinarily done by allowing cold water to pass through a chamber orjacket. which surrounds the cyl indcr of the engine, the water beingsupplied by a pump or tank. By this system a large amount of water iswasted. To save this expense and avoid the carrying of a large amount oncars whien are propelled by gasengines, I use the water over and overagain,

utilizing the heat of the water as it comes from the chamber or jacketof the engine to generate naphtha or other hydrocarbon gas in agenerator provided with a \\-'atcr-jacket, which generator in turn coolsthe water and 40 causes it to be returned to the chamber or jacket ofthe engine, on the principle of the difference in density or gravity ofhot and cold water.

In the accompanying drawings, liigure ll shows apparatus embodying myinvention, the gas-engine being shown in side elevation and thecarburetor and appliances used therewith in longitudinal section. Fig. 2is a crosssection on the line XX of Fig. 1: Fig. 3 is a 5 cross-sectionon the line Y Y.

.struction.

A generator D, of the kind hereinafter described or of any othersuitable character, is wholly or partially surrounded by a jacket K, asshown, being formed of outer and inner walls A R with ends a. The outerwall or shell A is provided with double heads, forming spaces T, T.,which serve as a protection for the various appliances used in the con-This reservoir or jacket K receives the heated water through the pipe 13as it comes from, the jacket or chamber ll, surrounding the cylinder Gof the gas-engine.

The generator 1) consists of a cylinder mounted on a hollow perforatedshaft V, which is provided with a pulley-m, by which the cylinder mayberotated. The cylinder D rotates in a chamber 0, containing a volatilehydrocarbon, and is provided with a series of floats (7, made asabsorbents and consisting of woven wire or cloth filled with someabsorbent material and attached to the inside of the cylinder 1). Thecylinder l) is made of open-workas, for instance, of woven wire or of asheet of perforated material like iron. The floats (1 take up thenaphtha in the chamber 0 and distribute it or allow it to fall in linestreams or as drops in the space in the upper part of the cylinder.

J is an inlet which permits the air to be forced into the carburetorthrough thehollow shaft, and N an outlet through which the carburetedair is carried away for use.

The pipe 13 is the exhaust for the heated water to pass out of thechamber ll of the engine and connects with the reservoir K, as shown inFig. 1. lly this means the hot water is allowed to drip over the shellof the generator and heats the naphtha more readily, and then as itbecomes cold settles and passes out by the exhaust-pipe 0 into thechamber 11 at L. Thus a circulation is kept up bet-ween the engine E andthe reservoir or jacket K, the explosion of the in the cylinder Gheating the water in the chamber or jacket ll and causing it to passthrough the pipe B to the jacket, where it becomes cold by heating thenaphtha and forming gas when it is returned to the jacket ll again.

My invention is designed especially forapplication to gas-engines whichare used to propel cars or vessels, and are supplied with gasmanufactured on the car or vessel as often as it'is needed. I do not,however, limit myself to this special application of the invention.

What I claim as my invention is The combination, substantially asdescribed, of a gas-generator, a j acket therefor, a gas-engine having acooling-jacket, and circulatingpipes, as described, for circulating aheating and cooling fluid through the jacket of the engine and thejacket of the generator.
